Filter is clean. Spark plug looks ok, i'd say the bike runs fine except for the consumption.
I also added an aftermarket exhaust (i can't see that increasing fuel consumption that way, plus it has no cats now...)
What may play a role is that i fitted a slightly bigger and less street oriented rear tire. I can see that decrease my mpg as i look at the odo to calculate it+ dirt tire will waste more energy on the slab. But not THAT much
Any idea what to look for, before i give a shot at putting everything back to stock (remove kev mod, stock filter and snorkle, stock exhaust) ?

What fuel are you using? 95RON? 97/98RON? E5 or E10? The latest E10 fuels (10% ethanol) will contribute to higher fuel consumption as ethanol has a lower energy content than petrol. The more ethanol the higher the fuel consumption will be for any given engine/road speed.
As they are sneaking up the ethanol content in forecourt petrol every year it is quite plausible that you are finding your bike's mpg gradually getting worse. Nine years ago here in the UK (when I bought my XTZ) the vast majority of petrol was E0 (no ethanol). By the end of 2018, when my bike is ten years old, it will almost all be E10, a completely different fuel from that the XT was originally designed to run on.
